Brazilian Barin/e 401 



7— Body moderately stout, convex, polished, black, the elytra slightly more 

 cuneate in the male; beak (cD not as long as the prothorax, rather thick, 

 strongly arcuate, evenly but only feebly tapering, rather coarsely, loosely 

 punctate, finely and sparsely beyond the antennae, or ( 9 ) as long as the 

 head and prothorax, equally thick and almost as strongly punctured basally, 

 but evidently, though not abruptly, less thick and subimpunctate in apical 

 four-sevenths; antennae blackish, medial (c?) or near two-fifths (9); pro- 

 thorax less convex than in the two preceding and shorter, fully a third wider 

 than long the sides broadly, feebly arcuate, parallel at base, abruptly con- 

 stricted at apex, the tubulation distinctly less than half as wide as the base 

 in both sexes; surface very minutely, remotely punctulate; elytra only a 

 fourth to third longer than wide, parabolic, barely as wide as the prothorax 

 and one-half to three-fifths longer, the humeri feebly swollen; grooves lrn- 

 punctate, a fifth or sixth as wide as the intervals, coarse and exarate apically; 

 intervals' with sparse infinitesimal punctulation; squamose line of the third 

 short and distinctly separated from the basal margin; pygidium small, 

 semicircular, closely punctate, a little more convex in the male, the latter 

 with the medio-apical region of the more punctate first ventral just visibly 

 impressed; presternum with two small apical foveae, only very briefly 

 prolonged- legs not as long as in the two preceding, the anterior femora (d 71 ) 

 finely dentate beneath. Length 4.7-5.O mm.; width 2.15-2.28 mm. _ Brazil

Body smaller and narrower, similar in color, lustre and sculpture; beak (c?) less 

 thick and longer, as long as the head and prothorax and differing also in 

 being very evenly cylindric, not at all tapering distally, evenly arcuate, the 

 sparse punctures less coarse; antenna? blackish, submedial; sides of the 

 prothorax evenly arcuate and slightly converging from base to the abrupt 

 apical constriction, the tubulation less than half as wide as the base; elytra 

 throughout nearly similar but narrower; pygidium shorter, the punctures 

 similarly deep but not so large and denser; impression at the apex of the 

 first ventral narrower, smaller and more definite; legs slender and shorter, 

 the anterior much shorter than in the preceding and with still more minute 

 inferior denticle. Length 3.9 mm.; width 1.73 mm. Brazil (Santarem).

8— Form rather stout, attenuately ovoidal, convex, deep black and polished; 

 beak ( 9 ) nearly as long as the head and prothorax, slender, smooth and 

 arcuate, gradually thickened, straighter and deeply but sparsely punctured 

 in about basal third; antennas piceous, at basal third; prothorax large, a 

 fourth wider than long, the sides parallel and feebly arcuate, gradually 

 strongly rounding in about apical half to the feeble sinuses defining the 

 constriction, which is very much feebler than in any of the preceding species, 

 the tubulation feeble and shorter, less than half as wide as the base; surface 

 with fine sparse punctulation, much more distinct than in the preceding 

 section and less sparse gradually toward the sides; basal lobe rather more 

 broadly rounded; elytra only a fifth longer than wide, barely as wide as the 

 prothorax and rather less than one-half longer, the oblique sides nearly 

 straight, the apex circularly rounded, with the usual broad reentrant sutural 

 angle; humeri moderately swollen; grooves fine, only a little coarser apically, 

 the first obsolete, except apically, and formed by a series of fine punctures; 

 squamose line almost a third the length, broader than in any of the preceding 

 and attaining the basal margin; pygidium densely punctate, only a little 

 wider than long, slightly oblique and distinctly convex; presternum with 

 two small approximate apical fovea;, not at all prolonged; legs rather long, 

 the anterior femora with a minute angular inferior tooth. Length 5.9 mm.; 

 width 2.65 mm. Brazil (Santarem). One specimen gradatus n. sp.
